DUMPlNG-GAR.

SPECIFICATION forming part of Letters Patent No. 296,088, dated April 1,1884.

Application filed August 30, 1883. (N model.)

marked thereon, which form a part of this specification.

My present improvements relate to a device for holding the car-bed in ahorizontal I posiof the draw-bar withthe truck and its central drafttimber,to the same in relation to a hinged platform on the truck for theoperator,

to means for tilting or dumping the car, and

to other novelties,which will fully appear from the followingdescription.

Figure 1 represents aside view of a car made in accordance with mypresent improvements; Fig. 2, a top view of the truck-frame, Fig. 3,

a top view of the frame of the car-bed; Fig. 4,

an end view of the car-body, and a cross-section of the truck in theline a: w of Fig. 1; and

Figs. 5 and 5 to are details.

My present improvements are designed more especially for a four-wheeleddumpingcar.

A is the car-body, and B the truck. I will first describe the devices 00 for holding the car-bed in position and. their action. Each of them ishung on apivot or bolt, d,and

. H is in the form of a stirrup, (see Fig; 9,) and has a singlecross-bar, e.

Each is connected, substantially as shown, to a short chain or rod,

1 o f,whose other end is connected to a long chain or rod, 9, thislatter rod or chain serving thus to connect f with f, so that bothstirrups on the same side of the car shallbe simultaneously operated bythe same movement of the handlever h. i These stirrups G G are pivotedon the inside of the sill of the car body or frame,

and the rods or chains f 9 also work on the inside of the same sill. 4

D D are fixed catches for the stirrups G, and

p they are bolted to the truck-frame, as seen.

That portion, 6, which engages with the stirrup when the latter is inits vertical position tapers or inclines at both sides and at the top,the under side, however, being straight, as seen. By these means,whenthe car-bed is in a horizontal position, and the hand-lever h isreleased or free, the stirrups drop by their own weight to theirvertical positions, and in so doing the loop of each stirrup embracesand receives the portion i of the catch. The carbody is thus firmly heldto its position, because the stirrups cannot ride off from thesecatches. The cross-bar 6 acts as a relief to the stirrup as the car istilted. The stirrups being released on one side of the car, and the carbeing tilted, the cross-bar of the stirrups on the opposite side of thecar strikes in their downward movement againstthe inclines on the upperside of the catches D D, and thus rides down these inclines and freesthe stirrups from the catches. The stirrups, it will be noticed, swinglengthwise of the car, and both thecatches D have their tapering ends inthe same direction or toward that end of the car from which the stirrupsare worked.

The latching and nnlatching devices for the swing-doors K are asfollows: Attached to the outside of the doors are slotted pieces Z, the

slots m of which are adapted to receive the notched end a of agravitating lever-latch, 0, which is pivoted at or on the under side ofthe outside sill, o, of the car-bed. This notch 19 the truck, and not tothe car-body, and its ad jacent parts are as follows: A central drafttimber, r, extends from end to end of the car, and to its ends areboltedblocks 8, upon which rests and slides the draw-bar; and t is astraddle-block or yoke through which this drawbar works, and on top ofthis yoke t is a hinged platform, a, for the operator to stand upon whendumping the car, pins or bars 1; projectj to act on the rocker.

ing above its surface to brace his feet, and to prevent the operatorfrom slipping or being thrown off as the car dumps. The platform may beraised vertically out of the way, when not in use, by a cord or chain,w, and when so raised it protects, in part, the mechanism by which thedumping is effected, and is not in the way of the brakeman in couplingor uncoupling the cars. The object of the block 8 is mainly to givesufficient elevation or height to the draw-bar, and it thusincidentally, also, affords a bed or foundation for the yoke 15, andthus brings the platform to a proper height for the workman. Theplatform, being on the truck, andnot on the car frame or floor, does nottilt when the car is dumped. The drawbar, also, being on the truck, andnot on the car, is not turned partly over when dumping, but preservesalways its true position for coupling, so that if the platform shouldoccupy its raised position and the bodies of two of my cars should bothbe in their tilted positions, yet they could be coupled together just aseasily as if they were not tilted. The platform may be always keptraised, when not in use, and held up by any appropriate cord, chain, orlatch, and when so raised it partially conceals and protects the tiltinggears or wheels.

The mechanism for lifting and dumping is as follows: A block, at, isbolted (as seen in Fig. 4) to each of the outside stringers, y, theseblocks also resting on the end beam, 1. The object of these blocks is toafford sufficient height for the fulcrum of a long lever, 2, (one oneach block,) and which, when pulled by the chain 3, which is fastened tothe other end of each lever, serves to push up the rocker 4 by means ofthe rod or link lever 5, which is pivoted to the rocker, and also to thelong lever 2. These levers 2, being long and fulcrumed at one end, andoperated by the chain at their other ends, have a powerful leverage Thischain is a linked one, and it passes from the end of one of the levers 2up and around a toothed wheel, 6, on the end of the car-body, thencedown and under a toothed wheel, 7, on the axis of the large gear-wheel8, thence up and over the toothed wheel9 on the car-body, and thencedownward and crossing itself to the extremity of the other long lever 2.It will be understood that the teeth or pins on the small wheels 6, 7,and 9 enter the links of the chain,- and the chain is taut enough tohave both levers 2 2 act in unison, so that when one link 5 is pushingone side of the rocker up the other one is pulling the opposite side ofthe rocker down. Ahandcrank, a serves to turn a cog-wheel, b whichoperates the large. gear-wheel 8, this gear serving to multiply power. Alarge round pin, 10, projects upward from the central draft-timber, r,and into and through an opening in the metal arch 11 of the rocker.Small round or conical pins 12 project upward from the plates 13 on theend beams, 1, the metal arch 13 being provided with suitable holes toreceive them. All these pins and holes are to prevent any sidewisesliding of the rocker, and the smaller ones also keep the body on therocker-sill in case of concussion during or after dumping. The piece orblock 14 extends centrally on the truck from rocker to rocker, andprevents endwise shifting of the bed. It is bolted at each end, as seen,to the draft-timber 1", thus giving the whole strength of both inholding the rocker-sill. The shallow stringers 15 are for givingstrength to the floor, and they are so located that when the dumpingtakes place they may come j ust inside of or bear against the inside ofthe outside sills of the truck and prevent therbed dropping off thetruck. In other words, the outside of stringer 15 would comeinside ofthe sill? ,which sill would thus form an absolute barrier against anyfurther lateral movement of the car-body. The gears 6 7 8 9 and thechain 3 are on the outside of the end of the carthat is, outside of theend sill or beam. The draft-timber r at'its ends has its top reduced orcut away, as seen at 1", and on part of such reduced surface is secured.the metal plate 1", provided with a metal pin or projection, r adaptedto enter a central hole in the metal arch ll of the rocker. The blocks 3s are also placed on a part of these reduced ends and this leaves aspacebetween the blocks and the unreduced portion of the draft-timber, withinwhich the rocker works. It will thus be seen that the rockers arepositively prevented from any shifting in a direction lengthwise of thecar, and the car cannot shift endwise, as the rocker is practically heldbetween two wallsone in front and one behind it.

The plate 1" is, as seen, in continuous line with the two plates 13 13,the three plates constituting the straight rocker-bed. To make .theseplates 13 13 andr all in one piece would be objectionable, as liable tobe bent or broken,

and, moreover, as the projection r should be integral with or firmlyconnected to the center of this metal bed, it is safer and better thatits plate or horizontal part 1 should not be too long. The draft-timberr, it will be seen, is firmly bolted through its entire or unreducedthickness to the top of the center bolster, a (see Fig. 7,) thus givinggreat strength and solidity, and contributing largely to support theload. In the truck-frame are stringers Z Z, placed inside of the outersills, 3 y, and be tween them and the car center; they are placedagainst the blocks as w, and are let into the truck-bolsters, as shown,and are firmly bolted to and through these bolsters. At the center ofthe car these stringers are of about equal other, and bolted to thelonger one, so as to leave at its ends the rabbets or reduced ends, asat r.

I claim a 1. In combination, the stirrups G, as made with the singlecross-bar e, and hung onthe sills of the car bed to swing in directionslengthwise of the car, the tapering catches D, fixed on the car-truck,and having their under sides straight, and the connections f and g andhand-lever h, all substantially as and for the purpose set forth.

2. The combination, substantiallyas shown and described, of the centraldraft-timber,r, on the truck, the block 8 thereon,the draw-bar restingon said block, and the straddle-block or yoke t, within which thedraw-bar works, the draft-timber block and yoke being bolted together. p

3. In combination, the draft-timber r on the truck-block s, yoke 15, anda platform, a, hinged above said yoke, as and for the purpose set forth.

4. In combination with the blocks 2;, bolted to the outside sills, y, ofthe truck, and resting on its end beam,1, the lovers 2, chain 3,linklevers 5, rocker 4, and the system of toothed gears on the car-body,the combination operating to tilt thebody by pushing either of thelink-levers 5 upward against the rocker.

5. In combination with the rockers of a dump-ear, the centraldraft-timber, r, on the truck-frame, made, as described, with reducedends, on which the rockers bear, and with a greater height or thicknessbetween the rockers, as and forthe purposes set forth.

6. In a four-wheeled side-dumping car, the combination, with a centerbolster, of, of a central draft-timber, r, centrally supported on andbolted at its center to the center of said bolster, said draft-timberbeing at its ends let into and secured to the rocker-bolsters, andforming a portion of the bed for the rockers.

7. In combination, the levers 2, links 5, chain 3, toothed gears 6 and 9on the car-body, large gear-wheel 8, having the toothed gear 7 on itsaxis, and driving-gear If, these parts being arranged for joint.operation substantially as and for the purposes set forth.
